Description

Die Erfindung bezieht sich auf einen tragbaren Datenträger, insbesondere eine Chipkarte, mit einer piezoelektrischen Schallerzeugungseinrichtung und einer elektronischen Schalteinrichtung.The invention relates to a portable data carrier, in particular a chip card, with a piezoelectric sound generating device and an electronic switching device.

Ein tragbarer Datenträger im Sinne der Erfindung ist ein Rechnersystem, bei dem die Ressourcen, das heißt Speicherressourcen und/ oder Rechenkapazität (Rechenleistung) begrenzt ist. Insofern sind tragbare Datenträger insbesondere Chipkarten (Smart Card, Mikroprozessor-Chipkarte) oder Token oder Chipmodule zum Einbau in Chipkarten oder Token. Derartige tragbare Datenträger umfassen üblicherweise einen Körper, in dem ein Mikroprozessor (CPU) angeordnet ist, und der jede beliebige standardisierte oder nicht standardisierte Gestalt haben kann, beispielsweise die Gestalt einer flachen Chipkarte ohne Norm oder nach einer Norm wie zum Beispiel ISO 7810 (zum Beispiel ID-1, ID-00, ID-000) oder die eines volumigen Tokens. Solche tragbaren Datenträger können desweiteren eine oder mehrere beliebige Schnittstellen für kontaktlose und/ oder kontaktbehaftete Kommunikation mit einem Lesegerät oder Datenverarbeitungssystem (zum Beispiel Personal Computer, Workstation, Server) haben. Der Mikroprozessor ist üblicherweise in einem Chipmodul integriert. Desweiteren können in solchen Datenträgern Displays, von außen betätigbare Schalteinrichtungen, insbesondere mechanische Taster, und Energiespeicher, insbesondere eine Batterie, enthalten sein.A portable data carrier in the sense of the invention is a computer system in which the resources, that is memory resources and / or computing capacity (computing power) is limited. In this respect, portable data carriers are, in particular, chip cards (smart card, microprocessor chip card) or tokens or chip modules for installation in chip cards or tokens. Such portable data carriers usually comprise a body in which a microprocessor (CPU) is arranged, and which may have any standardized or non-standardized shape, for example the shape of a flat chip card without a standard or according to a standard such as ISO 7810 (for example ID-1, ID-00, ID-000) or a voluminous token. Such portable data carriers may further have one or more arbitrary interfaces for contactless and / or contact communication with a reader or data processing system (eg, personal computer, workstation, server). The microprocessor is usually integrated in a chip module. Furthermore, in such data carriers displays, externally operable switching devices, in particular mechanical buttons, and energy storage, in particular a battery may be included.

Darüber hinaus können derartige Datenträger mit elektronischen Schallgebern, etwa als Lautsprecher oder Summer, ausgestattet sein. Es ist bekannt, derartige Schallgeber mittels piezokeramischen Schallgebermembranen zu realisieren. Dabei kommen dünne Piezoscheiben zum Einsatz, die über eine Metallisierung auf Vorder- und/oder Rückseite kontaktiert werden. Die elektrische Kontaktierung der Schallgebermembran erfolgt dabei durch Aufbringung des Schallgebers auf ein entsprechend ausgeführtes Leiterbahnlayout (beispielsweise durch Aufbringung auf eine als Inlayfolie in einer Chipkarte integrierten flexiblen Leiterplatte) oder mittels Drahtanschlüssen. Gegen Beschädigung und Umwelteinflüsse ist der Schallgeber geschützt, indem er durch eine Deckfolie, beispielsweise eine Kunststofffolie mit einer Dicke von 0,2 bis 0,5 mm, abgedeckt wird. Die akustischen Eigenschaften solcher piezoelektrischer Schallerzeugungseinrichtungen sind jedoch nicht ideal und haben nur einen sehr geringen Wirkungsgrad, das heißt, es ist damit nur eine geringe Lautstärke erzielbar.In addition, such media may be equipped with electronic sounders, such as a speaker or buzzer. It is known to realize such sounder by piezoceramic sounder membranes. In this case, thin piezoelectric disks are used, which are contacted via a metallization on the front and / or back. The electrical contacting of the sounder diaphragm is carried out by applying the sounder to a correspondingly designed interconnect layout (for example, by application to an inlay foil integrated in a chip card flexible circuit board) or by means of wire connections. Against damage and environmental influences, the sounder is protected by being covered by a cover sheet, for example a plastic film with a thickness of 0.2 to 0.5 mm. However, the acoustic properties of such piezoelectric sound generating devices are not ideal and have only a very low efficiency, that is, so it is only a small volume achievable.

Aus der DE 103 43 734 A1 geht ein Datenträger mit einem IC-Modul, einer Antenne zur drahtlosen Datenübertragung und einer aufladbaren Batterie hervor. Mit dieser Datenträgerkarte soll eine bewusste Aktivierung eines Identifikationsvorgangs bzw. einer Datenübertragung über einen größeren Abstand ermöglicht werden. Die Datenträgerkarte kann mit einem Piezoschallgeberelement versehen sein, dass das Betätigen eines Tasters durch einen spürbaren und hörbaren Schaltvorgang anzeigt.From the DE 103 43 734 A1 A data carrier with an IC module, a wireless data transmission antenna and a rechargeable battery emerges. With this data carrier card a deliberate activation of an identification process or a data transmission over a greater distance is to be made possible. The data carrier card can be provided with a piezoelectric sounder element which indicates the actuation of a pushbutton by a noticeable and audible switching operation.

Aufgabe der vorliegenden Erfindung ist es daher, den Wirkungsgrad von in tragbaren Datenträgern integrierten piezoelektrischen Schallerzeugungseinrichtungen zu verbessern.The object of the present invention is therefore to improve the efficiency of piezoelectric sound generating devices integrated in portable data carriers.

Dies wird erfindungsgemäß durch einen Datenträger nach Anspruch 1 erzielt.This is achieved according to the invention by a data carrier according to claim 1.

Durch diese Anordnung wird erreicht, dass der von der Schallgebermembran erzeugte Schall den Hohlraum der Schalteinrichtung durchlaufen kann, wobei der Hohlraum einschließlich etwaiger darin untergebrachter Elemente der elektronischen Schalteinrichtung als Resonanzkörper wirkt. Insbesondere kann eine äußere Abdeckung des Hohlraums als Membran wirken und die Abstrahlung des erzeugten Schalls zusätzlich verstärken.By this arrangement it is achieved that the sound generated by the sounder diaphragm can pass through the cavity of the switching device, wherein the cavity, including any elements of the electronic switching device housed therein acts as a resonator. In particular, an outer cover of the cavity can act as a membrane and additionally enhance the radiation of the generated sound.

Andererseits kann die den Hohlraum überspannende Abdeckdung derart elastisch deformierbar sein, dass durch Drücken der Abdeckung in den Hohlraum hinein die elektronische Schalteinrichtung betätigt wird. Die Abdeckung bildet bei dieser Anordnung somit gleichzeitig einen Bestandteil eines mechanischen Tasters, so dass sie funktional sowohl der Schallerzeugungseinrichtung als auch der elektronischen Schalteinrichtung zugeordnet ist.On the other hand, the cover spanning the cavity may be elastically deformable such that by pressing the cover into the cavity, the electronic switching device is actuated. The cover thus forms in this arrangement at the same time a part of a mechanical button, so that it is assigned functionally both the sound generating device and the electronic switching device.

Die elektronische Schalteinrichtung kann aber auch einen in anderer Weise ausgebildeten mechanischen Taster umfassen, sofern ein mit der piezoelektrischen Schallerzeugungseinrichtung verbundener Hohlraum verbleibt, der als Resonanzkörper für die von der Schallerzeugungseinrichtung erzeugten Schallwellen dient. So kann der mechanische Taster beispielsweise eine in dem Hohlraum angeordnete Schnappscheibe umfassen. Die Schnappscheibe kann in dem Hohlraum wiederum mittels der vorgenannten, den Hohlraum überspannenden elastisch deformierbaren Abdeckung fixiert sein. Verschiedene Varianten zum Einbau derartiger mechanischer Taster in tragbare Datenträger, insbesondere Chipkarten, werden beispielsweise in der WO 2006/136229 A1 beschrieben. Die dort beschriebenen mechanischen Taster besitzen teilweise eine Schnappscheibe, kommen aber teilweise auch ohne Schnappscheibe aus. Soweit eine Schnappscheibe vorgesehen ist, wird diese mittels der elastisch deformierbaren Abdeckung heruntergedrückt und schnappt in eine Position, in welcher sie elektrische Anschlüsse miteinander leitend verbindet. Ohne eine solche Schnappscheibe dient die elastisch deformierbare Abdeckung selbst als elektrisch leitendes Verbindungselement im heruntergedrückten Zustand.However, the electronic switching device can also comprise a mechanical button formed in another way, provided that a cavity connected to the piezoelectric sound generating device remains, which serves as a resonating body for the sound waves generated by the sound generating device. For example, the mechanical probe may comprise a snap-action disc arranged in the cavity. The snap-action disc can in turn be fixed in the cavity by means of the aforementioned elastically deformable cover spanning the cavity. Different variants for the installation of such mechanical buttons in portable data carriers, in particular chip cards are, for example, in the WO 2006/136229 A1 described. Some of the mechanical buttons described there have a snap-action disc, but some of them also come without a snap-action disc. As far as a snap-action disc is provided, it is pressed down by means of the elastically deformable cover and snaps into a position in which it connects electrical connections to one another in a conductive manner. Without such a snap-action disc, the elastically deformable cover itself serves as an electrically conductive connecting element in the depressed state.

Vorteilhafter Weise sind zumindest ein elektrisches Kontaktelement der elektronischen Schalteinrichtung und die piezoelektrische Schallerzeugungseinrichtung auf einer gemeinsamen Leiterplatte angeordnet. Dadurch lässt sich der Aufwand zur Herstellung des tragbaren Datenträgers reduzieren.Advantageously, at least one electrical contact element of the electronic switching device and the piezoelectric sound generating device arranged on a common circuit board. As a result, the effort for the production of the portable data carrier can be reduced.

Insbesondere kann die Leiterplatte als flexible Folie ausgebildet sein. Dann lässt sie sich vorteilhaft als sogenannte Inlayfolie in einen kartenförmigen Datenträger integrieren. Bei einem mehrschichtig laminierten Kartenkörper kann die Leiterplatte z.B. eine laminierte Schicht des Kartenkörpers bilden. Der Hohlraum zur Aufnahme der elektronischen Schalteinrichtung kann vorteilhaft nach vollständiger oder teilweiser Fertigstellung des laminierten Kartenkörpers in den Kartenkörper eingefräst werden, insbesondere wenn der Kartenkörper im Heißlaminierverfahren hergestellt wird, wobei mit dem Fräsen des Hohlraums gleichzeitig Kontaktanschlüsse für die elektronische Schalteinrichtung am Grund des Hohlraums freigelegt werden. Es ist aber auch möglich, den Hohlraum dadurch zu bilden, dass mehrere mit Durchbrüchen versehene Schichten so übereinander liegend miteinander laminiert werden, dass die Durchbrüche den Hohlraum im Kartenkörper bilden.In particular, the circuit board may be formed as a flexible film. Then it can be advantageously integrated as a so-called inlay in a card-shaped disk. In a multilayer laminated card body, the circuit board may be e.g. form a laminated layer of the card body. The cavity for receiving the electronic switching device can advantageously be milled into the card body after complete or partial completion of the laminated card body, in particular when the card body is produced in the Heißlaminierverfahren, with the milling of the cavity simultaneously exposed contact terminals for the electronic switching device at the bottom of the cavity , However, it is also possible to form the cavity in that a plurality of openings provided with openings are laminated one above the other so that the openings form the cavity in the card body.

Die elektronische Schalteinrichtung und die piezoelektrische Schallerzeugungseinrichtung sind erfindungsgemäss auf einander gegenüberliegenden Seiten der Leiterplatte angeordnet. In diesem Falle ist eine Durchbrechung in der Leiterplatte vorgesehen, um die von der Schallerzeugungseinrichtung erzeugten Schallwellen in den oberhalb der Leiterplatte gelegenen Hohlraum zu leiten. Der Vorteil dieser Ausgestaltung besteht darin, dass sowohl für die piezoelektrische Schallerzeugungseinrichtung als auch für die elektronische Schalteinrichtung der auf der Leiterplatte verfügbare Raum maximal ist. Durchkontaktierungen durch die Leiterplatte können vorgesehen sein, um die elektronische Schalteinrichtung und die piezoelektrische Schallerzeugungseinrichtung miteinander und/ oder mit einem auf einer Seite der Leiterplatte angeordneten Mikrocontroller zu verbinden.The electronic switching device and the piezoelectric sound generating device according to the invention are arranged on opposite sides of the circuit board. In this case, an opening in the circuit board is provided to direct the sound waves generated by the sound generating means in the cavity located above the circuit board. The advantage of this embodiment is that both for the piezoelectric sound generating device and for the electronic switching device of the available space on the circuit board is maximum. Vias through the printed circuit board may be provided to connect the electronic switching device and the piezoelectric sound generating device to each other and / or to a microcontroller disposed on one side of the printed circuit board.

Gemäß einer besonderen Weiterbildung der Erfindung kann die piezoelektrische Schallerzeugungseinrichtung mit der elektronischen Schalleinrichtung auch derart gekoppelt sein, dass sie bei Betätigung der Schalteinrichtung ein Geräusch erzeugt, sozusagen als akustische Rückkopplung bei einem Schaltvorgang. Dies ist insbesondere bei Tastschaltern günstig, die bei Betätigung keiner besonderen Verformung unterliegen, beispielsweise im Falle elektronischer Tastschalter.According to a particular embodiment of the invention, the piezoelectric sound generating device with the electronic sound device may also be coupled so that it generates a sound when operating the switching device, so to speak as acoustic feedback in a switching operation.

Fig. 1 zeigt eine erfindungsgemäß ausgebildete Chipkarte 1 in einer schematischen Schnittdarstellung. Die Darstellung ist nicht streng auf eine Schnittebene begrenzt, sondern zeigt auch gegeneinander versetzt angeordnete Komponenten der Chipkarte 1. Aus Gründen der Anschaulichkeit ist die Darstellung stark unmaßstäblich ausgeführt. Eine zugehörige Aufsicht auf die Chipkarte 1, bei der auch im Inneren der Chipkarte 1 angeordnete Komponenten gezeigt sind, ist in Figur 2 dargestellt. Fig. 1 shows a chip card 1 formed according to the invention in a schematic sectional view. The representation is not strictly limited to a sectional plane, but also shows offset from each other Components of the chip card 1. For the sake of clarity, the representation is carried out strongly to scale. An associated plan view of the chip card 1, in which components arranged inside the chip card 1 are also shown, is shown in FIG FIG. 2 shown.

Die Chipkarte 1 weist einen Kartenkörper 2 auf, der bezüglich seiner Abmessungen gemäß der Norm ISO/IEC 7810 ausgebildet sein kann und beim dargestellten Ausführungsbeispiel aus einer unteren Halbschale 3 und einer oberen Halbschale 4 zusammengesetzt ist. Die Halbschalen 3 und 4 sind vorzugsweise aus Kunststoff gefertigt. Zwischen den Halbschalen 3 und 4 ist eine flexible Leiterplatte 5 mit einem ersten Mikrocontroller 6, einer Batterie 7, einem Taster 8 und einer Anzeigeeinrichtung 9 angeordnet. Der Taster 8 und die Anzeigeeinrichtung 9 sind in Figur 1 unmittelbar übereinander dargestellt, sind aber tatsächlich zueinander versetzt, wie sich aus der Aufsicht gemäß Figur 2 ergibt. Der Taster 8 ist darüber hinaus nur symbolisch dargestellt und wird anhand der Figuren 3 bis 5 noch im einzelnen erläutert.The chip card 1 has a card body 2, which may be designed in terms of its dimensions according to the standard ISO / IEC 7810 and in the illustrated embodiment of a lower half-shell 3 and an upper half-shell 4 is composed. The half shells 3 and 4 are preferably made of plastic. Between the half-shells 3 and 4, a flexible printed circuit board 5 with a first microcontroller 6, a battery 7, a button 8 and a display device 9 is arranged. The button 8 and the display device 9 are in FIG. 1 shown directly above each other, but are actually offset from each other, as is apparent from the supervision FIG. 2 results. The button 8 is also shown only symbolically and is based on the FIGS. 3 to 5 still explained in detail.

In einer zweistufig ausgebildeten Vertiefung 10 in der oberen Halbschale 4 ist ein Chipmodul 11 angeordnet und über elektrische Verbindungselemente 12 mit der Leiterplatte 5 verbunden. Die elektrischen Verbindungselemente 12 können insbesondere als "flexible Bumps" ausgebildet sein, die einen gewissen Spielraum bei der Positionierung des Chipmoduls 11 zulassen, so dass das Chipmodul 11 bündig zur Oberfläche des Kartenkörpers 2 ausgerichtet werden kann. Zur mechanischen Fixierung ist das Chipmodul 11 mit dem Kartenkörper 2 verklebt. Das Chipmodul 11 weist einen zweiten Mikrocontroller 13 auf, in dem beispielsweise eine Anwendungssoftware der Chipkarte 1 implementiert ist. Das Chipmodul 11 weist desweiteren ein Kontaktfeld 14 auf, das von einem nicht figürlich dargestellten externen Gerät insbesondere für eine Datenübertragung kontaktierbar ist. Das Kontaktfeld 14 kann aber auch entfallen, wenn ausschließlich eine kontaktlose Datenübertragung vorgesehen ist.In a two-step recess 10 in the upper half-shell 4, a chip module 11 is arranged and connected via electrical connection elements 12 to the circuit board 5. The electrical connection elements 12 can be designed, in particular, as "flexible bumps", which allow a certain freedom in the positioning of the chip module 11, so that the chip module 11 can be aligned flush with the surface of the card body 2. For mechanical fixation, the chip module 11 is glued to the card body 2. The chip module 11 has a second microcontroller 13 in which, for example, an application software of the chip card 1 is implemented. The chip module 11 further has a contact pad 14, which can be contacted by an external device (not shown in FIG. 1), in particular for data transmission. The contact field 14 can also be omitted if only a contactless data transmission is provided.

Der erste Mikrocontroller 6 dient beim dargestellten Ausführungsbeispiel der Ansteuerung der Anzeigevorrichtung 9, so dass der zweite Mikrocontroller 13 über den ersten Mikrocontroller 6 Zugriff auf die Anzeigevorrichtung 9 hat. Der Taster 8 kann je nach Ausführungsbeispiel unterschiedliche und insbesondere auch mehrere Aufgaben übernehmen. Beispielsweise kann er zur Aktivierung der Anzeigevorrichtung 9 dienen und/ oder zum Zurücksetzen des ersten Mikrocontrollers 6 in einen definierten Zustand.The first microcontroller 6 is used in the illustrated embodiment, the control of the display device 9, so that the second microcontroller 13 via the first microcontroller 6 has access to the display device 9. The button 8, depending on the embodiment different and in particular take over several tasks. For example, it can be used to activate the display device 9 and / or to reset the first microcontroller 6 in a defined state.

Unterhalb der flexiblen Leiterplatte 5 gegenüberliegend zum Taster 8 ist eine piezoelektrische Schallerzeugungseinrichtung 30 vorgesehen. Die Schallerzeugungseinrichtung 30 ist über die Leiterplatte 5 von dem ersten und/oder zweiten Mikrocontroller 6,13 ansteuerbar. Die von der Schallerzeugungseinrichtung erzeugten Schallwellen gelangen durch Öffnungen 31 in der Leiterplatte 5 hindurch in einen Hohlraum 32, in welchem der Taster 8 untergebracht ist.Below the flexible printed circuit board 5 opposite to the button 8, a piezoelectric sound generating device 30 is provided. The sound generating device 30 can be controlled by the first and / or second microcontroller 6, 13 via the printed circuit board 5. The sound waves generated by the sound generating device pass through openings 31 in the circuit board 5 in a cavity 32, in which the button 8 is housed.

Figur 3 zeigt eine Ausführungsvariante der Chipkarte 1 mit einem konkreten Ausführungsbeispiel der hier als mechanischer Taster 8 ausgebildeten elektronischen Schalteinrichtung in einer schematischen Schnittdarstellung. Die Darstellung ist wiederum aus Gründen der Anschaulichkeit stark unmaßstäblich. Der Kartenkörper 2 der Chipkarte 1 ist hier aus mehreren Kunststofffolien 15 hergestellt. Bei der dargestellten Variante wurden sechs Kunststofffolien 15 verwendet. Als Material für die Kunststofffolien 15 eignet sich beispielsweise PVC. Zuvor werden auf wenigstens eine der Kunststofffolien 15 Leiterbahnen 16 aufgebracht, beispielsweise durch Bedrucken mit Silberleitpaste, wodurch die betreffende Kunststofffolie die flexible Leiterplatte 5 bildet. Die Leiterbahnen 16 dienen der Ausbildung elektrischer Verbindungen und/ oder als Antenne. FIG. 3 shows an embodiment of the chip card 1 with a concrete embodiment of the here designed as a mechanical button 8 electronic switching device in a schematic sectional view. The representation is in turn for the sake of clarity strongly unmaßstäblich. The card body 2 of the chip card 1 is made here of a plurality of plastic films 15. In the illustrated variant, six plastic films 15 were used. As a material for the plastic films 15, for example, PVC is suitable. Before 15 printed conductors 16 are applied to at least one of the plastic films, for example by printing with silver conductive paste, whereby the plastic film in question, the flexible circuit board. 5 forms. The conductor tracks 16 serve to form electrical connections and / or as an antenna.

Der Taster 8 ist in einer Kavität 17 im Kartenkörper 2 integriert. Die Kavität 17 ist zweistufig ausgebildet, so dass sie eine umlaufende Schulter 18 aufweist. Die Kavität 17 wird von der Leiterplatte 5 nach unten begrenzt. Auf dieser Leiterplatte 5 ist ein erster Schaltkontakt 19 in Form einer Kreisscheibe beispielsweise durch Aufbringen von Silberleitpaste ausgebildet. Weiterhin ist dort ein zweiter Schaltkontakt 20 ausgebildet, der die Form eines einseitig offenen Rings aufweist und den ersten Schaltkontakt 19 in einem Abstand konzentrisch umgibt. Dies ist in Figur 4 schematisch in Draufsicht gezeigt. Die Schaltkontakte 19 und 20 gehen jeweils in Leiterbahnen 16 über, die ebenfalls mittels Silberleitpaste ausgebildet sein können. Die Schaltkontakte 19, 20 und/ oder Leiterbahnen 16 können ebenso durch dünne Metallstreifen gebildet werden. Über den Schaltkontakten 19, 20 sitzt in der Kavität 17 eine metallische Schnappscheibe 13. Um einen Kurzschluss der beiden Schaltkontakte 19, 20 im unbetätigten Zustand der Schnappscheibe 23 zu verhindern, ist der Schaltkontakt 19 in einem Bereich 21 auf seiner Oberfläche gegenüber der darüber liegenden Schnappscheibe 23 elektrisch isoliert.The button 8 is integrated in a cavity 17 in the card body 2. The cavity 17 is formed in two stages, so that it has a circumferential shoulder 18. The cavity 17 is bounded by the circuit board 5 down. On this circuit board 5, a first switching contact 19 is formed in the form of a circular disk, for example by applying Silberleitpaste. Furthermore, there is a second switching contact 20 is formed, which has the shape of a ring open on one side and the first switching contact 19 concentrically surrounds at a distance. This is in FIG. 4 shown schematically in plan view. The switching contacts 19 and 20 each go in interconnects 16, which may also be formed by silver conductive paste. The switching contacts 19, 20 and / or printed conductors 16 can also be formed by thin metal strips. To prevent a short circuit of the two switching contacts 19, 20 in the unactuated state of the snap-action disc 23, the switching contact 19 is in a region 21 on its surface relative to the overlying snap-action disc 23 electrically isolated.

Die Schnappscheibe 13 greift in eine Aussparung 24 eines Deckels 25 ein. Der Deckel 25 besteht aus einer Deckelfolie 26, insbesondere einer FR4-Folie, die gegebenenfalls außenseitig mit einer Metallschicht 27 beschichtet ist. Der Deckel 25 wird beispielsweise mittels eines Heißsiegelklebers im Bereich der Schulter 18 der Kavität 17 derart mit dem Kartenkörper 2 verklebt, dass er die Kavität 17 abdeckt und bündig mit der Oberfläche des Kartenkörpers 2 abschließt. Anstelle einer vollständigen metallischen Schnappscheibe kann wahlweise auch eine teilweise metallische Schnappscheibe mit Kunststoffdom verwendet werden.The snap disc 13 engages in a recess 24 of a lid 25 a. The lid 25 consists of a cover film 26, in particular a FR4 film, which is optionally coated on the outside with a metal layer 27. The lid 25 is adhesively bonded to the card body 2 in the region of the shoulder 18 of the cavity 17, for example, by means of a hot-seal adhesive such that it covers the cavity 17 and terminates flush with the surface of the card body 2. Instead of a complete metallic snap-action disc, a partially metallic snap-action disc with a plastic dome can optionally also be used.

Der Taster 8 wird durch Druckausübung auf den Deckel 25 betätigt. Dadurch wölbt sich der Deckel 25 zum Boden der Kavität 17 hin und verschiebt und verformt die Schnappscheibe 23 so, dass diese berührend an beiden Schaltkontakten 19 und 20 anliegt. Sobald der Druck auf den Deckel 25 aufgehoben wird, federt dieser in Folge seiner eigenen Elastizität und der Elastizität der Schnappscheibe 23 in seine Ausgangslage zurück. Dadurch wird der berührende Kontakt zwischen der Schnappscheibe 23 und den beiden Schaltkontakten 19 und 20 aufgehoben und die über die Schnappscheibe 23 ausgebildete elektrische Verbindung wieder unterbrochen. Durch die Schnappscheibe 23 ist bei Betätigung des Tasters 8 eine taktile Rückmeldung spürbar.The button 8 is actuated by applying pressure to the lid 25. As a result, the lid 25 bulges toward the bottom of the cavity 17 and shifts and deforms the snap disc 23 so that it touchingly contacts both switch contacts 19 and 20. As soon as the pressure on the lid 25 is released, this springs back into its initial position as a result of its own elasticity and the elasticity of the snap-action disc 23. As a result, the contacting contact between the snap-action disc 23 and the two switching contacts 19 and 20 is canceled and the electrical connection formed via the snap-action disc 23 is interrupted again. By the snap disk 23 is a tactile feedback can be felt upon actuation of the button 8.

Auf der der Schnappscheibe 23 gegenüberliegenden Oberfläche der flexiblen Leiterplatte 5 ist die piezoelektrische Schallerzeugungseinrichtung 30 angeordnet und über dortige Leiterbahnstrukturen elektrisch leitend letztendlich mit dem Mikrocontroller 13 des Chipmoduls 11 verbunden. Über Öffnungen 31 ist die piezoelektrische Schallerzeugungseinrichtung räumlich mit dem auf der gegenüberliegenden Seite der Leiterplatte 5 liegenden Hohlraum 17 verbunden.On the surface of the flexible printed circuit board 5 opposite the snap disk 23, the piezoelectric sound generating device 30 is arranged and finally electrically connected to the microcontroller 13 of the chip module 11 via conductor track structures there. Via openings 31, the piezoelectric sound generating device is spatially connected to the lying on the opposite side of the circuit board 5 cavity 17.

Figur 5 zeigt diesen Aufbau in weiterem Detail mit einigen kleineren Unterschieden. Beispielsweise kommt hier der Deckel 25 ohne metallische Beschichtung 24 aus und kann selbst opak ausgebildet sein. FIG. 5 shows this structure in more detail with some minor differences. For example, the lid 25 comes out without a metallic coating 24 and may itself be made opaque.

Wie Figur 5 zu entnehmen ist, sind beidseitig der Leiterplatte 5 Leiterbahnen 16 vorhanden, einerseits für die Schnappscheibe 23 und andererseits für die piezoelektrische Schallerzeugungseinrichtung 30. Letztere ist über Kontaktflächen mit der Leiterbahn 16 verbunden. Durchkontaktierungen 32 durch die Leiterplatte 5 hindurch können vorgesehen sein, um die Leiterbahnstrukturen auf den beiden gegenüberliegenden Seiten der Leiterplatte 5 miteinander elektrisch leitend zu verbinden.As FIG. 5 can be seen, 5 printed conductors 16 are present on both sides of the circuit board, on the one hand for the snap-action disc 23 and on the other hand for the piezoelectric sound generating means 30. The latter is connected via contact surfaces with the conductor track 16. Through-holes 32 through the printed circuit board 5 can be provided around the printed conductor structures on the two opposite sides of the circuit board 5 to connect electrically conductive.

Der von der piezoelektrischen Schallerzeugungseinrichtung 30 abgegebene Schall gelangt durch die Öffnungen 31 der Leiterplatte 5 hindurch in den Hohlraum 17 und kann diesen nahezu ungehindert durchlaufen. Der Hohlraum 17 sowie die darin angeordnete Schnappscheibe 23 dienen als Resonanzkörper. Der Deckel 25 wirkt zusätzlich als Membran und kann die Abstrahlung des erzeugten Schalls verstärken.The sound emitted by the piezoelectric sound generating device 30 passes through the openings 31 of the printed circuit board 5 into the cavity 17 and can pass through it almost unhindered. The cavity 17 and the snap disk 23 arranged therein serve as resonance bodies. The lid 25 also acts as a membrane and can amplify the radiation of the generated sound.

Die piezoelektrische Schallerzeugungseinrichtung kann vorteilhaft als piezokeramische Schallgebermembran ausgebildet sein. Handelsübliche piezokeramische Schallgebermembranen, wie sie in Chipkarten zum Einsatz kommen, sind kreisförmig und haben einen Gesamtdurchmesser im Bereich von 6,5 bis 15 mm und eine Gesamtdicke im Bereich von 0,15 bis 0,65 mm. Die Abmessungen der üblicherweise in Chipkarten eingesetzten Taster haben ähnliche Durchmesser, so dass die Anordnung der piezoelektrischen Schallerzeugungseinrichtung 30 in dem Hohlraum 17 unter der Druckoberfläche eines an sich bekannten Tasters einfach zu realisieren und mit geringem Aufwand in bestehende Fertigungsabläufe integrierbar ist.The piezoelectric sound generating device can be advantageously designed as a piezoceramic sounder diaphragm. Commercially available piezo ceramic sounder membranes, as used in smart cards, are circular and have a total diameter in the range of 6.5 to 15 mm and a total thickness in the range of 0.15 to 0.65 mm. The dimensions of the probes commonly used in smart cards have similar diameters, so that the arrangement of the piezoelectric sound generating device 30 in the cavity 17 under the pressure surface of a known per se button easy to implement and with little effort into existing production processes can be integrated.

Anstelle der Schnappscheibe 23 kann der mechanische Taster auch durch eine Folientaste ersetzt werden, bei der der Kontakt zwischen den Kontaktflächen 19 und 20 durch das Aufeinanderdrücken zweier metallisierter Folien, bzw. des innenseitig metallisierten Deckels 25 auf die Kontaktflächen der Leiterplatte 5, bewirkt wird. Auch dazu sind in der WO 2006/136229 A1 verschiedene Ausführungsbeispiele angegeben.Instead of the snap disc 23, the mechanical button can also be replaced by a membrane key, in which the contact between the contact surfaces 19 and 20 by the pressing together of two metallized films, or the inside metallized cover 25 on the contact surfaces of the circuit board 5, is effected. Also in the WO 2006/136229 A1 various embodiments indicated.

Die piezoelektrische Schallerzeugungseinrichtung 30 kann insbesondere dazu dienen, beim Drücken des Tasters 8 ein Geräusch als akustische Rückmeldung für die Betätigung des Tasters zu erzeugen.The piezoelectric sound generating device 30 can in particular serve to generate a sound as an acoustic feedback for the actuation of the button when the button 8 is pressed.
